ZO (Zee-Oh) Trombone Plastic Silver Model There are no noticeable scratches or stains. The rotary valve axis is stiff and doesn't move smoothly with the lever. It moves if you operate the axis directly, but please consider this if you are able to perform maintenance. Above all, it's light! Unlike metal, it puts less strain on your shoulders and arms, making it great for long practice sessions. ▫️ Unique Appearance Even though it's "silver," the metallic plastic coating reflects light and stands out! It might even look good at a concert! ▫️ Affordable but Produces Sound The sound quality isn't as good as metal, but it sounds surprisingly good! Suitable for casual practice or events. ▫️ Easy Maintenance The parts are simple and easy to handle, and you only need to wipe the slide part regularly. ⸻ Accessories: Mouthpiece (plastic) Case included (from when purchased)
